New high performance antistatic masterbatch

To keep the sparks from flying

The exclusive high performance antistatic agent from GRAFE has a resistivity value in the range of 106 to 109 ohm-meters. This high antistatic protection helps to prevent sudden discharge of technical devices, reduces dust attraction on surfaces and minimizes the danger of sudden explosions. It offers special protection to sensitive electronic devices.


The long-term effect of our antistatic masterbatch is documented by over three years of research. Protection begins as soon as the end product is produced. The high performance antistatic masterbatch can be combined with color masterbatches or fillers. Our customers save costs through low dosaging without compromising on design and production flexibility.


Applications for the new GRAFE high performance antistatic masterbatch include:


  • Injection molding

  • Blow molding

  • Staple fibers

  • Non-woven fabrics

  • Deep-drawn parts

  • PVC products

  • Transparent and colorless articles in the non-food segment

Glossy and metallic masterbatch

Unlimited design options with the Effect Masterbatch from GRAFE


The polypropylene film composite creates vibrant, streak-free color effects on any surface. The resulting innovative glossy and metallic effects reveal a whole new range of design options for our customers.


Plastic components in cars should be cost-efficient, high quality and light. However, in addition to these features, the “feel” of the plastics and the mechanical properties are also very important. Effect surfaces are often challenging for manufacturers when flow lines appear on the end product at material build-up points and joint lines. Up until now, the only option has been to refinish the faulty parts in a costly post-processing step.


The GRAFE Group supplies the innovation for new designs without any post-processing or compromise on quality. Our polypropylene film composite creates vibrant, streak-free color effects on every grained surface. Simplest process control combined with greatest variability guarantees maximum cost-efficiency.


The polyolefin film is colored with a specially developed masterbatch and has a wall thickness of less than 400 µm. Because the film and the component carrier are both made of polypropylene, optimal bonding is guaranteed in the injection molding process with no pretreatment required.


Combinations are also possible: Base and cover film can be produced as transparent or translucent. The cover film is then equipped with the desired transparent metallic effect. In this combination, it is also possible to illuminate the composite. Vehicle interiors can be designed to appeal to customers on an emotional level by combining the right colors in an attractive arrangement of the components.


The appeal of the vehicle’s exterior finish can also be carried over to the plastics applications in the interior. The glossy and metallic effects in the PP film composite make it possible to have different grains on the component. Flexibility is greatly increased simply by changing the film.


The composite of PP film and PP material means that recycling the end product is simpler because it is made from only one type of material.

UV masterbatch for PC twin-wall sheets

Sunglasses for plastics


Ultraviolet light is vital for maintaining nature – it enables growth and preserves the biological equilibrium. Ultraviolet light is a relatively high-energy radiation and this presents an ongoing challenge for the producers of masterbatches.


Ultraviolet radiation causes plastics and colors to age. The durability of plastic parts is thus greatly reduced. UV-absorbers are therefore added to plastics to make them more resistant.


Twin-wall sheets are normally polycarbonate based. Unlike PMMA or polyolefine, polycarbonate does not stand up well against high-energy radiation. Over time it suffers a loss of mechanical strength and yellows noticeably.


In general, manufacturers of PC compounds add approximately 5 to 6 percent UV absorbers. These compounds are used primarily in coextrusion processes. The thickness of the layer and therefore the concentration of the UV absorbers on the surface, determine the guarantee and durability of the twin-wall sheets in outdoor applications.


GRAFE’s newly developed UV masterbatches for PC twin-wall sheets offer the advantage of highly concentrated additive masterbatches and contain 50 percent of the active ingredient in addition to optical brighteners and a color improver. The masterbatch is dosed at 10 to 12 percent with pure PC and coextruded on to the twin-walled sheets.


GRAFE’s flexible production technology allows the use of any type of UV absorber to meet customer demands in terms of both technology and price. It allows savings of up to 30% in comparison with traditional products. Additional savings are achieved through quick transport, simple storage and the fact that customers need one tenth less of the masterbatch than is normally required.

Cool Black applications in synthetic fibers

Simply cool


Cool Black is a masterbatch for dark or black colors that prevents dark surfaces made of PA and PET yarns from heating up as a result of thermal absorption. Cool Black significantly reduces thermal absorption in contrast to the behavior of carbon pigments.


Cool Black guarantees that thermal radiation (in the near infrared or NIR area) can only be absorbed above 700nm. The lower thermal absorption means that the product’s surface is perceived as much cooler and more pleasant to touch.


Thanks to the chemical compatibility of the colorants used in PA and PET, an alternative formulation with the same effect for PP is also available.

Protection against counterfeiting

Originals only


The GRAFE Group is presenting an innovative type of additive masterbatch. It is a new combination of chemical substances for product marking. This marking can be detected both qualitatively and quantitatively in the end product by means of x-ray fluorescence analysis.


The additive masterbatch has been developed for applications with synthetic yarns and fibers, as well as for commodities and PP-, PA- and PET-based specialties. The active ingredients in the marker masterbatch can be used in many other plastics. They cannot be destroyed in the normal processing of thermoplastics and are resistant to solvents, scrubbing solutions, dye baths and spinning oils.


It is also possible to combine colors in the masterbatch – a complete solution for higher demands.


We provide our customers with technical support and assistance in evaluating marker masterbatches with our own in-house XRF analysis and with initial validation in production.

Masterbatches for luminescent plastics

A light in the darkness


Plastics that glow in the dark are especially popular in the toy industry and in the production of fashion articles and promotional items. Luminescent pigments are also important for brand authentication and document security.


In the past, products could only be made luminescent using a green-gray color. With the new innovative masterbatches from GRAFE, products can now glow in vibrant red, green, yellow or blue. The colors remain stable in the daylight allowing designers a whole new range of options.


Masterbatches for film applications

Brilliant shine


The GRAFE Group provides masterbatches and compounds for numerous application areas. In the area of film application, we are offering an absolute novelty in plastics production.


The ability of coloring films – especially very thin films – requires a formulation with high dipersibility. The real challenge lies in the inclusion of the metallic particles. These have a structure which is relatively large in relation to the film thickness making it difficult to process. Our research department has, however, found a solution.


For example, we have developed the exterior case design for a complete luggage series from the manufacturer Samsonite. Our high-quality film for the surface of the case features a special design with metallic effects and a carbon look. This masterbatch has good processability and high color brilliance combined with a metallic gloss.


Biocolen ¬– biologically degradable masterbatches

Ecologically compatible colors


Ecology and sustainability are two topics that are gaining importance not only in industry but also in our society. New standards and stricter regulations have led to a change of thinking in the production of plastics.


Under the brand name Biocolen, the GRAFE Group offers its customers masterbatches for coloring biologically degradable plastics. Plastics on the basis of sustainable raw materials are leading the way to a closed reutilization cycle which saves crude oil.


A revolution: Masterbatches that are not only biologically degradable but that are also available in the same vibrant colors and with the same technical properties as classic masterbatches.


In the development of our biodegradable masterbatches, we have tested our products for compostability, strength, resistance to light, weather and aging. These tests have shown that the films completely degrade and are no longer detectable after only two. The Biocolen therefore comply with Euro-Norm EN 13432.


Products made of bioplastics with inorganic mineral pigments or organic synthetic colorants are limited in their compostability.


Biocolen masterbatches are produced on the basis of plant colorants and are completely biologically degradable.


Spectrafoil Optical Lightener – Masterbatch for greenhouse films

For an abundant harvest


Our Spectrafoil Optical Lightener is a masterbatch for greenhouse films which transforms UV light into visible light. This increases the photosynthetic active radiation (PAR) and results in early harvests, improved yields and higher product quality.


The material has already been used successfully in the cultivation of strawberries, tomatoes, basil and cut flowers. Depending on the type of plant, yields can be increased by up to 30 percent. Plants branch out more and grow faster and more continuously. The amount of dry substrate in the fruits is also increased.


We recommend the use of this masterbatch in the regions of central and eastern Europe, especially in spring and autumn when the sun‘s radiation is weaker. It can also be combined with other additives.

Spectrafoil NIR Cooling Masterbatch

Dried out stalks are a thing of the past with GRAFE


Our Spectrafoil NIR Cooling Masterbatch reduces heat development in green houses because it absorbs and reflects the sun’s radiation in the near infrared range (NIR). Yet at the same time, it allows photosynthetic active radiation (PAR) to enter. Foils treated with this masterbatch have a cooling effect without limiting plant photosynthesis.


This product is especially suitable for warmer climate zones. Successful tests have been conducted in Spain and Cyprus on tomatoes, peppers and cucumbers. Yields increased by 15 percent and leaves had less tendency to dry out. The production facilities where the foils were used lost less heat over night and required less water. They also needed less energy for additional cooling systems due to the cooling effect of the foils.

Spectrafoil Antifungi masterbatch

No trace of spores


Particularly in the production of food crops, keeping plant disease in check is of central importance. GRAFE is solving this problem with its masterbatch Spectrafoil Antifungi. Greenhouse foils that have been treated with this masterbatch modify the sun’s radiation as it passes through and prevent fungal spores from multiplying. This significantly reduces the amount of fungicide which is needed.


Spectrafoil Antifungi not only prevents crop failures, it improves crop yields. Eliminating the use of chemical agents in agriculture leads to healthier food.

Antimicrobial properties of light-colored synthetic yarns and fibers

No chance for germs


The spread of germs remains a great challenge particularly in medical environments. The GRAFE Group has recognized this problem and acted. For over 10 years our scientists have been researching methods for the antimicrobial and antibacterial treatment of plastics.


The latest results are synthetic staple fibers for operational use. Unlike traditional products, these fibers can be dyed to lighter colors. The new development is based on substances supplied by the company AMISTec in Kössen, Tirol.


The material features strong and long-lasting antimicrobial effectiveness, a wide spectrum of activity and no induction of resistance. It is also effective against multi-resistant pathogens, contains no nanoparticles and is not inactivated by sweat or proteins.
